GRAND RAPIDS (WZZM) - The liquor license for a Grand Rapids bar is in jeopardy after four people were shot early Friday morning.

The violence broke out at the New Roosevelt Bar on Grandville Avenue SW. Police say the bar has had more than its share of problems and that's why the liquor license is in question.

Back in November, there was a double shooting outside the bar. One person died.

Bryan Martinez, who helps manage the bar says they do everything they can to keep people safe. "Somebody acted a fool," says Martinez. He was bartending last night when the chaos broke out.

It was just after 2 a.m. when he heard someone yell out that a person outside the front door had a gun. That's when patrons tried to rush out the back door. "The security guard was by the back door. It came open and someone started shooting."

The security guard and three people inside the bar were shot. Sgt. Scott Rifenberg says, "Shots did come from parking lot and went through backside door."

Martinez helped the victims. "I tied a belt around the security guards leg. I put a shirt around his leg. The person with a neck wound, I put pressure on it until police got there."

Police say the victims' injuries are non-life-threatening.

This is the second shooting in three months. Martinez says they have five security guards.

"I had two at the door, two floaters, and one at back door. They wand them, they get patted down, and patted down a second time." Martinez says he meets with police about security and goes to neighborhood watch meetings. "The biggest complaints around here were gang activity."

Police say, everyone seems to be cooperating with the investigation and they have good leads. Martinez says he's at loss about what more he can do about the security.

"I'm going to continue to go on. I have a passion for what I do. It's unfortunate." Martinez says he hopes police will patrol the area a little more, given the recent violence.

No arrests have been made in the shootings. If you have any information, your asked to call Grand Rapids Police or Silent Observer at (616) 774-2345.
